Amarok has gone quiet on a couple of times, but this is the first time it has crashed, so I'd say it's not readily reproducible :(

Maybe it is, I just had another crash.

Which version of the phonon-backend-gstreamer do you use? This should be fixed since version 4.6, see also bug 290706

Sorry, forgot to specify my setup:
Ubuntu 12.04, amd64. I'm running the following version:

$ apt-cache policy phonon-backend-gstreamer
phonon-backend-gstreamer:
  Installed: 4:4.7.0really4.6.0-0ubuntu1
  Candidate: 4:4.7.0really4.6.0-0ubuntu1
  Version table:
 *** 4:4.7.0really4.6.0-0ubuntu1 0
        500 http://se.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages
        100 /var/lib/dpkg/status

I didn't reflect on it at the time, but when I choose 'next song' in amarok main gui, the title really didn't fit the current playlist. Is there any state that is saved that could perhaps screw things up?

Please submit another report, then, as this crash clearly is related to gstreamer
